ワークアウトボトル シリコーンパッキン

The two gasket sizes fit snugly into the bottle lid and cap without any fuss, and the silicone feels dense enough to hold up over time. My bottle no longer leaks when I shake it during my workout.

It’s a relief to find these exact-size silicone seals—the smaller one fits the cap perfectly and stops any leaks during my morning commute.

Replacing the old worn-out seals was a five-minute job and the bottle's back to being leak-proof. The smaller one for the cap area is a perfect match, and the silicone feels dense enough to hold up over time.
